Summary0004122: HLR Returns No Edges for Shape
DescriptionForum discussion

OCC HLR (HLRBRep_Algo) returns empty result for attached shape. DRAWEXE fails to display result of HLR with message "Error: AIS_Shape::Compute() HLR Algorithm has failed ()".
Steps To ReproduceOpen attached FCStd file and create new View for object "Bullet". Empty view will be created with no error messages.

Changing View to Coarse mode produces result.

Note: FC in OSX will display bullet shape, but Windows or Linux.
Additional InformationDRAWEXE fails to display shape in "algo" mode, but displays shape in "polyalgo" mode.
